  1. PIC port d’informació científica PIC Tier1 Report Josep Flix Molina (jflix@pic.es) PIC Tier-1 Manager Fernando Lopez Muñoz (flopez@pic.es) PIC Network Manager LHCONE Workshop (CERN), 10th February 2014

  2. Plans about networking upgrades • LAN: April 2014. Replace old aggregation switches (8x 3Com 5500) with new ones (4x Nexus 2248) • 48x1Gbps Ethernet ports, up to 4x10Gbps fiber uplinks • LAN: During Run2 ramp-up of resources, a new module of 48x10Gbps ports will be needed in our core router (Nexus 7009). We foresee to install it before. • LAN: The need of new firewall to fully adopt IPv6 (mid-2015) • Some implementations are being reviewed (HW vs. SW) • WAN: upgrade to 40 Gbps or 100 Gbps links? (mid-2015) LHCOPN/ONE workshop @ CERN 10/11 Feb.

  3. Network connectivity to WLCG Sites (I) • LHCOPN • Primary link 10 Gbps • 56 PBytes of data moved on 2013 – Average of 12 hours of link saturation per month in Run1 • Backup link 1 Gbps • 15 incidents with an average duration of ~3h (mostly fiber cuts) • This link is only for T0  T1 transfers • T1 T1 transfers redirected uses Internet LHCOPN/ONE workshop @ CERN 10/11 Feb.

  4. Network connectivity to WLCG Sites (II) • Internet • Actually T2 T1 transfers uses this connection of 10 Gbps • LHCONE • NREN to install the needed VRF router. Deployment expected before end of February 2014 (we are working as of today in close contact with them) • 10 Gbps (link shared with LHCOPN) • Connection from RedIRIS VRF to GEANT VRF expected at 10 Gbps • Once this is in production in PIC, national Tier2s will connect at 10 Gbps (CIEMAT-LCG2,…) • Then, the plan is to move our Internet connectivity to 1 Gbps (at low priority). LHCOPN/ONE workshop @ CERN 10/11 Feb.

  5. Concerns • LHCOPN is a well-known network, robust and stable, and it offers good functionality • Although it might be improved, we are well satisfied with it – it works, don’t change it! • We’re sure LHCONE will be successful at our site, but we don’t have operational experience yet. • We hope to participate more actively in the P2P project soon • WLCG is deploying perfSONAR-PS instances: • It measures the health of the links (bwd, lat) • How we handle the network monitoring? Are you interested in it? We are! • LHCOPN/ONE monitoring and alarming system? Are there network shifts expected? LHCOPN/ONE workshop @ CERN 10/11 Feb.
